Isimiso sokusebenza se-pneumatic valve kanye nendlela yokusebenza

Ukuthengwa kwe-valve ye-pneumatic kuphela imininingwane ecacile, izigaba, ingcindezi yokuhlangabezana nezidingo zokuthengwa komkhuba, ingasetshenziswa ukulawula ukugeleza komoya, amanzi, umusi, zonke izinhlobo zemidiya ezonakalisayo, udaka, uwoyela, insimbi ewuketshezi kanye nemithombo ye-radioactive nokunye. izinhlobo zoketshezi. Ayiphelele esimweni somnotho wemakethe yamanje. Ngenxa yokuthi abakhiqizi bamavalvu womoya wokuncintisana komkhiqizo, ngamunye embonweni womklamo ohlanganisiwe we-pneumatic valve, ukuqamba okusha okuhlukile, kwakha awabo amazinga ebhizinisi kanye nobuntu bomkhiqizo. Ngakho-ke, kudingekile kakhulu ukubeka phambili izidingo zobuchwepheshe ngokuningiliziwe lapho uthenga ama-valve womoya, futhi uxhumanise nabakhiqizi ukuze uthole ukuvumelana, njengesijobelelo senkontileka yokuthengwa kwe-valve yomoya.
Ukulungiswa kwe-valve ye-pneumatic:
Ekusebenzeni kwemishini, i-valve ye-pneumatic idlala indima ebalulekile, ukusetshenziswa kwayo akumele kube nekhono kakhulu, ikhwalithi kufanele futhi iqinisekiswe ngesikhathi esifanayo, lokhu kuzodinga ukugcinwa okudingekayo kwe-valve yomoya, i-valve kanye nesidingo sokugcinwa ngesayensi yesayensi. isimo sengqondo, ukwenza umsebenzi wokugcinwa kwe-valve ukufeza inhloso yomphumela nokusetshenziswa.
Amanothi okugcinwa kwansuku zonke kwe-valve ye-pneumatic:
I-1, i-valve kufanele igcinwe ekamelweni elomile nelingenawo umoya, zombili iziphetho zendlela kufanele zivalwe.
I-2, isitoreji sesikhathi eside se-valve kufanele sihlolwe njalo, *** ukungcola, futhi endaweni yokucubungula ehlanganiswe ngamafutha e-anti-rust.
3. Ngemuva kokufakwa, ukuhlolwa okuvamile kufanele kwenziwe. Izinto zokuhlola eziyinhloko ziyi 1) ukugqokwa kwe-sealing surface. (2) ukugqokwa kwentambo ye-trapezoidal yesiqu ne-stem nut. (3) ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile, uma konakele, kufanele kushintshwe ngesikhathi. (4) Ngemuva kokulungiswa nokuhlanganisa ama-valve, ukuhlolwa kokusebenza kokuvala uphawu kufanele kwenziwe.
Amanothi okugcinwa kwe-valve ye-pneumatic:
1. Inhloso yokusetshenziswa nokugcinwa kwe-valve ukwandisa ukuphila kwe-valve nokuqinisekisa ukwethembeka kokuvula nokuvala.
2, intambo ye-valve stem, imvamisa ukungqubuzana ne-valve stem nut, ukusebenzisa amafutha amancane aphuzi owomile, i-molybdenum disulfide noma i-graphite powder, ukuthambisa.
I-3, ungavamisi ukuvula nokuvala i-valve, kodwa futhi uphendule njalo isondo lesandla, engeza i-lubricant kumcu we-stem, ukuvimbela ukuluma.
4, i-valve yangaphandle, ukwengeza umkhono ovikelayo esiqwini se-valve, ukuvimbela imvula, iqhwa, ukugqwala kothuli.
5. Uma ivalvu iwumshini okufanele ihanjiswe, engeza amafutha okugcoba ku-gearbox ngesikhathi.
6, gcina i-valve ihlanzekile njalo.
7. Njalo hlola futhi ugcine ubuqotho bezinye izingxenye zevalvu. Uma i-nati ehleliwe ye-handwheel iwa, kufanele ifaniswe futhi ayikwazi ukusetshenziswa, ngaphandle kwalokho izogaya isikwele sengxenye engenhla ye-valve stem, kancane kancane ilahlekelwe ukwethembeka komdlalo, futhi ngisho ayikwazi ukuqala.
8, unganciki ku-valve ukusekela ezinye izinto ezinzima, ungami ku-valve.
I-9, i-valve stem, ikakhulukazi ingxenye yentambo, ukusula ngokuvamile, i-lubricant ingcolile ngothuli ukuze ishintshwe entsha, ngoba uthuli luqukethe imfucumfucu eqinile, intambo elula yokugqoka kanye ne-stem surface, ithinta impilo yesevisi ye-pneumatic single. i-valve yokulawula isihlalo.
Isimiso sokusebenza se-pneumatic valve kanye nendlela yokusebenza
Umgomo wokusebenza we-valve ye-pneumatic wethulwa:
Iphuzu eliphumayo le-valve ye-pneumatic yi-actuator ye-pneumatic. Imodi yayo yokusebenza ukushayela ukushintshwa kwe-valve nokulungisa ngosizo lomoya ocindezelweyo. Ngokusho kwesigaba semodi yokulawula ingahlukaniswa ngohlobo lokushintshwa kwe-valve ye-pneumatic kanye nohlobo olulawulayo lwezigaba ezimbili. I-valve yokushintsha umoya wohlobo iqukethe ama-actuator womoya, ama-valve, indlela yokusebenza eyenziwa ngesandla, izingcezu ze-sanlian zokwelashwa komthombo womoya, ama-solenoid valve, amaswishi anomkhawulo, isixhumo, isixhumi esisheshayo, i-compressor yomoya, uqhoqhoqho njll. izingcezu, i-muffler, isixhumi sepulaki esheshayo singakhethwa ngokukhululekile ngokuya ngesimo sesayithi. I-valve yokulawula umoya ihlanganisa i-pneumatic actuator, i-valve, indlela yokusebenza ngesandla, i-valve yegesi kagesi, unxantathu wokwelapha umthombo womoya, i-muffler, isixhumi esisheshayo sepulaki, ipayipi lokucindezela umoya, njll., lapha indlela yokusebenza ngesandla, i-muffler, isixhumi esisheshayo khethwa ngokukhululekile ngokuya ngemibandela yendawo. Ama-valve we-pneumatic asetshenziswa kabanzi ekulawuleni okuzenzakalelayo kwamanzi, umoya, umusi, udaka, uwoyela, insimbi ewuketshezi kanye neminye imidiya.
Izinyathelo zokuqapha ukusebenza kwe-pneumatic valve:
Okokuqala, vula i-valve, kufanele unake:
1. Hlola ukuthi ingabe uwoyela ongakwazi kusihlungi somoya kanye ne-pressure reducer seyengeziwe yini (uwoyela wokugcoba);
2, hlola ukuthi ipayipi lihlanzekile uma kunemfucumfucu, kunconywa ukuthi ufake isihlungi sepayipi phambi kwe-valve
3. Bese uqhubeka nokulawula umsuka
4. Ngemva kokulungisa ingcindezi yomthombo womoya, uhlobo lwepiston (0.4-0.7) kg, uhlobo lwefilimu (0.1-0.2) kg
5, ekunikezeni amandla (uhlobo lokushintsha luyi-voltage) noma (uhlobo olulawulayo lwamanje noma isignali ye-voltage)
6, bese ulungisa noma uvule isilawuli
Okubili, vala i-valve, kufanele unake:
1, nqamula isignali yokulawula (i-voltage noma yamanje)
2. Lungisa ingcindezi yokuhlunga umoya ibe ziro
Indlela yokusebenza kwe-pneumatic valve:
1. Ukuvuleka nokuvalwa kwe-valve yomoya kusendleleni yewashi. I-valve ye-pneumatic kunethiwekhi yepayipi yokuvula nokuvala, ukuguqulwa kokuvula nokuvala akufanele kube kuningi, ngisho ne-valve enkulu yobubanzi kufanele ibe ku-200-600 revolution.
2. Ukuze kube lula ukuvulwa nokuvalwa kwe-valve ye-pneumatic, umzuzu wokuvula nokuvala kufanele ube ngaphansi kuka-240N-m ngaphansi kwesimo sokucindezela kwe-plumber. Ukuvulwa kwe-valve ye-pneumatic kanye nokuphela komsebenzi wokuvala kufanele kube i-tenon yesikwele, futhi ubukhulu kufanele bufane, futhi bubheke phansi, ukuze abasebenzi bakwazi ukusebenza ngokuqondile phansi. Ama-valve anama-wheel plate awafanele amanethiwekhi amapayipi angaphansi komhlaba.
3. Ukuze kuqinisekiswe ukuthi ukuvuleka nokuvalwa kwe-valve ye-pneumatic akweqisi, umugqa wesikali wezinga lokuvula nelokuvala le-valve yomoya kufanele uphonswe ngokuphawulekayo kukhava yebhokisi le-gearbox noma igobolondo lepuleti lokubonisa ngemva koshintsho. yokuqondisa, futhi kufanele ibheke phansi. Lapho ukulungiswa kokuvula nokuvala kunembile, kufanele kukhiywe ngama-rivets.
4. I-valve ye-pneumatic yokuvula nokuvala ukusebenza kunethiwekhi yepayipi ayifanele ukusebenza kahle. Uma indlela yokusebenza nepuleti lokubonisa levalvu yomoya ingaphansi kwamamitha angu-1.5 phansi, kufanele kumiswe indawo yenduku yokunweba ezinzile futhi enokwethenjelwa, ukuze abasebenzi bakwazi ukubona futhi basebenze phansi.
